CROSS-REFERENCE TO RELATED APPLICATION

This patent application is a 35 USC § 371 U.S. national stage of International Application No. PCT/CN2018/099139 filed on Aug. 7, 2018, which claims priority to a Chinese Patent Application No. 201710687866.8, filed in China on Aug. 11, 2017, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of wireless communication technology, and in particular, relates to a frequency-band state processing method and a frequency-band state processing device.

BACKGROUND

In a 5th Generation (5G) mobile communication system, a User Equipment (UE) probably only supports a relatively narrow operating bandwidth (such as 5 MHz), whereas a cell of a network device may support a relatively wide bandwidth (such as 100 MHz), the narrow bandwidth part, in which the UE operates, in the wide bandwidth is a Bandwidth Part (BWP).

For example, as shown in FIG. 1, assuming that a cell of a network device supports a frequency bandwidth of 100 MHz, then the frequency bandwidth of 100 MHz is divided into a plurality of frequency-band areas, and a single frequency-band area corresponds to a single BWP, such as BWP 1, BWP 2, BWP 3, and BWP 4.

However, in a case that a plurality of different BWPs are configured, the related art does not define how the UE chooses to use the plurality of different BWPs for information interaction with a base station. Thus, the UE cannot manage a BWP state of a BWP, which leads to a lower bandwidth utilization.

The UE 01 shown in FIG. 3 may perform operations performed by a UE in the frequency-band state processing method provided by some embodiments of the present disclosure. For example, in one implementation, the communication interface 12 in the UE 01 may be used to receive control signaling sent by a network device: the processor 10 in the UE 01 may be used to configure, according to a state configuration indication included in the control signaling, a BWP state of a BWP corresponding to a BWP identifier included in the control signaling.

The portion 20 is mainly used for transmitting and receiving radio frequency (RF) signals and conversion between RF signals and baseband signals. The portion 21 is mainly used for baseband processing and used for controlling the base station 02, etc. The portion 20 may usually be called a transceiver unit, a transceiver, or a transceiver circuit, etc. The portion 21 is usually a control center of the base station 02, which may be generally called a processing unit, and is used to control the base station 02 to perform the steps performed by the base station 02 (i.e., a serving base station) in FIG. 4.

The transceiver unit of the portion 20 may also be called a transceiver, etc., which includes an antenna and a radio frequency (RF) unit, wherein the radio frequency unit is mainly used for radio frequency processing. Optionally, a device for implementing a reception function in the portion 20 may be regarded as a reception unit and a device for implementing a transmission function may be regarded as a transmission unit, that is, the portion 20 includes the reception unit and the transmission unit.

In addition, all functions in the portion 21 may be integrated into one chip in actual implementation, or a part of functions may be integrated into one chip in actual implementation, and the remaining of the functions may be integrated into one or more other chips in actual implementation. Some embodiments of the present disclosure are not limited to these.

The base station 02 shown in FIG. 4 may perform operations performed by a network device in the frequency-band state processing method provided by some embodiments of the present disclosure. For example, in one implementation, the portion 21 in the base station 02 may be used to generate control signaling; the portion 20 in the base station 02 may be used to send the control signaling to a UE.

It should be noted that, the structure of the device shown in FIG. 4 does not constitute a limitation to the base station, and may include more or fewer components than those shown in the figure, or may combine some components, or may arrange different components. Some embodiments of the present disclosure are not limited to these.

Based on interaction between the UE 01 and the base station 02 in the system shown in FIG. 2, each module or component of the UE 01 shown in FIG. 3, and each module or component of the base station 02 shown in FIG. 4, some embodiments of the present disclosure provide a frequency-band state processing method. This method describes in detail an interaction process between the UE 01 and the network device in the system shown in FIG. 2. FIG. 5 is a schematic flowchart illustrating a frequency-band state processing method provided by some embodiments of the present disclosure; specifically, as shown in FIG. 5, the frequency-band state processing method may include steps S501 to S504.

Step 501: generating, by a network device, control signaling.

The control signaling includes at least one BWP identifier and a state configuration indication, the state configuration indication includes an activation indication or a deactivation indication, and the state configuration indication is used to indicate that a UE configures a BWP state of a BWP corresponding to the BWP identifier included in the control signaling. A BWP identifier is used to uniquely identify a BWP.

The activation indication in the control signaling is used to indicate that the UE activates the BWP corresponding to the BWP identifier included in the control signaling: the deactivation indication in the control signaling is used to indicate that the UE deactivates the BWP corresponding to the BWP identifier included in the control signaling.

Illustratively, the network device configures at least one BWP for the UE and sends BWP configuration information to the UE; after the network device configures the at least one BWP for the UE, the network device generates control signaling including at least one BWP identifier and a state configuration indication.

For example, it is assumed that the network device configures 5 different BWPs for the UE, which are BWP 1, BWP 2, BWP 3, BWP 4, and BWP 5, respectively. The control signaling includes a BWP identifier of the BWP 1 (such as 1), a BWP identifier of the BWP 2 (such as 2), a BWP identifier of the BWP 3 (such as 3), a BWP identifier of the BWP 4 (such as 4), and a BWP identifier of the BWP 5 (Such as 5). It is assumed that the activation indication may be used to indicate that the UE activates the BWP 2 corresponding to the BWP identifier 2, the BWP 4 corresponding to the BWP identifier 4, and the BWP 5 corresponding to the BWP identifier 5; the deactivation indication may be used to indicate that the UE deactivates the BWP 1 corresponding to the BWP identifier 1 and the BWP 3 corresponding to BWP identifier 3.

It should be noted that, whether the state configuration indication included in the control signaling generated by the network device is the activation indication or the deactivation indication may be determined according to requirements of the UE (such as a link state, a channel quality, etc.).

S502: sending, by the network device, the control signaling to the UE.

After the network device generates the control signaling, the network device may send a Radio Resource Control (RRC) message to the UE, and the RRC message carries the control signaling. For example, the base station 02 sends the RRC message to the UE through the portion 20.

Step 503: receiving, by the UE, the control signaling sent by the network device.

The UE receives, through the communication interface 12, the control signaling sent by the network device.

Illustratively, as shown in FIG. 6, FIG. 6 shows a schematic diagram of a network architecture of a UE provided by some embodiments of the present disclosure. The network architecture may include: a physical layer, a Media Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, and an RRC layer.

The physical layer is at a lowest level in the network architecture, which may provide transmission media and interconnected devices for data communication between devices, and provide a reliable environment for data transmission. The MAC layer is mainly responsible for controlling and connecting a physical medium of the physical layer. The RLC layer provides segmentation and retransmission services for user data and control data. The PDCP layer may process RRC messages on a control plane and Internet Protocol (IP) packets on a user plane. The RRC layer is responsible for broadcasting system information and transmitting dedicated control information.

Illustratively, after the physical layer of the UE receives the control signaling, the physical layer of the UE delivers at least one BWP identifier and a state configuration indication in the control signaling to the MAC layer or the RRC layer of the UE, so that the MAC layer or the RRC layer performs a corresponding processing on the at least one BWP according to the state configuration indication.

S504: configuring, by the UE according to the state configuration indication, a BWP state of a BWP corresponding to the BWP identifier included in the control signaling.

The processor 10 of the UE may configure the BWP state of the BWP corresponding to the BWP identifier included in the control signaling according to the activation indication; or the processor 10 of the UE may configure the BWP state of the BWP corresponding to the BWP identifier included in the control signaling according to the deactivation indication.

Illustratively, it is assumed that the control signaling includes a BWP identifier 2 and a BWP identifier 4 and an activation indication. The processor 10 of the UE may configure the BWP state of the BWP 2 corresponding to the BWP identifier 2 according to the activation indication, that is, the BWP state of the BWP 2 is configured as an activated state, and the processor 10 of the UE may configure the BWP state of the BWP 4 corresponding to the BWP identifier 4 according to the activation indication, that is, the BWP state of the BWP 4 is configured as the activated state.

Some embodiments of the present disclosure provide a frequency-band state processing method. The UE may configure the BWP state of the BWP corresponding to the BWP identifier according to at least one BWP identifier and the state configuration indication included in the received control signaling, and may flexibly manage the BWP state of the BWP, thereby increasing a gain of frequency diversity and further improving a frequency-band utilization rate.

Further, because the state configuration indication may be sent by the network device according to the requirements of the UE (such as the link state, the channel quality, etc.), the UE may be indicated to activate or deactivate an appropriate BWP according to the requirements of the UE (such as the link state, the channel quality, etc.), which may ensure a data transmission quality of the UE, thereby reducing a packet loss rate and a power loss of the UE.

A BWP identifier is used to uniquely identify a BWP.

Illustratively, after the network device configures at least one BWP for the UE, the network device may send the BWP configuration information to the UE through the portion 20, wherein the BWP configuration information includes the BWP identifier of the at least one BWP, the BWP type of the at least one BWP, and/or the BWP initial state of the at least one BWP.

For example, the network device configures 5 different BWPs for the UE, which are BWP 1, BWP 2, BWP 3, BWP 4, and BWP 5, respectively. The BWP configuration information sent by the network device to the UE includes the BWP identifier, the BWP type, and/or the BWP initial state of the BWP 1: the BWP identifier, the BWP type, and/or the BWP initial state of the BWP 2; the BWP identifier, the BWP type, and/or the BWP initial state of the BWP 3; the BWP identifier, the BWP type, and/or the BWP initial state of the BWP 4; and the BWP identifier, the BWP type, and/or the BWP initial state of the BWP 5.
